Inglis 1C
Basic information
Sample name: Inglis 1C
Reference: D. R. Ruez Jr. 2002. Mammalian taphonomy of the early Irvingtonian (late Pliocene) Inglis 1C fauna (Citrus County, Florida). Southeastern Geology 41(3):159-168 [ER 4002]
Geography
Country: United States
State: Florida
Coordinate: 29° 0' 43" N, 82° 40' 5" W
Coordinate basis: stated in text
Time interval: Early Pleistocene
Geography comments: no details on chronology are given, and the early Irvingtonian is currently Early Pleistocene
Environment
Lithology: sandstone
Taphonomic context: pitfall trap
Habitat comments: "a paleosinkhole within the Upper Eocene Ocala Limestone" and "Pale-yellow quartz sands dominate the clastic fraction of the Inglis 1C infillings"
"articulated elements do not occur" because "large mammals were disarticulated after deposition in the sinkhole... evidence of predation at Inglis 1C is limited to a carnivoran tooth puncture on a single Odocoileus phalanx" and carnivoran finds "are probably not a result of denning", so animals presumably fell or climbed into the sinkhole with no "fluid or carnivoran transport"
